I need to add about 10 lbs of hardness increaser to my water to bring my level up to 350. I like to start it at the top and let it fall down over the course of time. My question is I have read you should add about 2-3 lbs at a time and let it circulate about 4-6 hours and repeat. Is this necessary to do or could it be added at the same time in increments in a shorter amount of time. Usually what I do is fill up a pail with water and put about 2.5-3 lbs at a time mix it up and let it disolve and pour in the pool in front of a jet and wait a few minutes and repeat.
Is this correct or is that too much at one time?
